That would work if their reference 3090s were not notoriously hitting 110C on the memory junction with any significant memory load, spinning fans to the volume of Concorde flying cruise speed. Other manufacturers actually had that problem covered.

I do not understand how Nvidia thinks putting ONE tiny fan on something that draws 200 watts is a sane decision. Back in the day they were even using centrifugal fans just to add a few extra decibels.

  I wish they were that good! The card is actually 350W. I run mine with power limit 250W. Fortunately the slowdown of minGPT training is only ~3% with this setup.

      To be pedantic 1.03 * 3 is ~1.093, which is much less than 1.4 = 350/250, so the behavior is still quite surprising.

  There's 2 fans, one on each side.

    Not on most of the cards they make. I was talking in more general terms, every large format GPU should have 2-3 large ass fans so it can run quieter with them running at low rpm instead of one screaming its bearings off. Given that the 3090 has 2 of them makes me think it would probably actually melt or explode with just one, they wouldn't give you an extra 2 dollars worth of fans on a $2k product for free you know.

      I think there's a bit of prejudice going on in this thread based on experiences in the past. The earlier FEs with 1-fan design at the end were indeed not great but the current gen is very nice. I have the 3080TI FE and it's a really solid card. Very well made, strong metal case. Nowhere is there any exposed board (ESD risks!) except for the obviously necessary PCI header. Fans run fine and are not too noisy and it doesn't overheat. My last card was an MSI 1080Ti beast and it was just a poor design. Yeah it was a bit quieter but physically and mechanically it wasn't as well designed as this by far. It seemed to have been designed much more for looks than performance.

  You're replying to a comment about the 3090. I'm not aware of any single-fan 3090s.
